Jumbo frames

Hi, first post and looking for a bit of advice!

We have x6 3650's stacked as our core switches in our data centre, (I'm aware the 3650 isn't really designed to be a core switch, and we have experienced issues with the buffers becoming overloaded as a result, but it's what we have and need to deal with it for now).

We're looking at implementing jumbo frames on the stack in an effort to boost the performance primarily of iscsi traffic.

As it's a global command to the entire stack, are we going to experience a degradation of performance for all the other devices connected directly to it, (to name a few, some physical servers, VPN server, WLC and checkpoint firewalls).

I'm after opinions from people who have implemented jumbo frames and seen benefits and also those who have had issues!

Many thanks

Rich
